Mump 0911 12 Front End Alignment Basics Lower Control Arms

For '67-'73, Ford came up with a better idea-lower control arms that adjust via an eccentric to move the lower arm in or out. Move the arm out to achieve negative camber. Move it in to get positive camber. The downside to this eccentric is movement when you hit a pothole. It could move, causing an unwanted change in camber.
